Preparing biological samples for examination

• Organisms are made up of cells.
• Most organisms are multicellular and have cells that are specialised to do a particular job.
• Microscopes are needed to study cells in detail.
• Plant cells are found in onion epidermal cells.
• Animal cells are found in the cheek cells.
• Other biological structures include human hair or animal fur.
• The aim of the experiment is to stain cells for examination with a light microscope and examine a range of cells and other structures with a microscope to understand their basic structure.
